Electrical Machines

A dc shunt generator, when driven without any excitation, showed an open circuit voltage of 12 V. When the field winding was excited, the voltage dropped to zero. It happened because

field resistance was higher than critical resistance

there was no residual magnetism in the field circuit

field winding was wrongly connected

there was a break in the armature circuit

field resistance was higher than critical resistance

there was no residual magnetism in the field circuit

field winding was wrongly connected

there was a break in the armature circuit
